• If you are trying to use Boolean operators, they must be ALL CAPS: hoc viet anh - ((anh tang) OR (hanh trang)) cua tong cong dan ((than tap) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc viet anh - ((anh tang) or (hanh trang)) cua tong cong dan ((than tap) OR (toan tap))*".
